System Design Interviews Without the Panic
A repeatable framework for the round that scares engineers most.
System design rounds reward structure. The candidates who panic are the ones without a framework. Build one.
Step-by-step
- Clarify requirements (functional + non-functional) — never skip
- Estimate scale with back-of-envelope math
- Sketch the high-level architecture before going deep on any component
- Pick 2–3 components to deep-dive (whichever the interviewer signals on)
- End with bottlenecks, trade-offs, and what you'd evolve next
Practice 6–8 archetypes (chat, feed, URL shortener, rate limiter, ride-sharing, search) until the framework feels boring.
